SAMUEL HAVERSTICK, OF CHICAGO, ILLINOIS.

LIN OLE UM.

To all whom it 7;: a3, concern Be it known that I SAMUEL HAVERSTICK, citizen of the United tates, residing at Chicago, in t e county of Cook and State of inois, have invented a certain new useful Improvement in Linoleum, ofjwhich the following is accompanying drawings, forming a part of t 15 specification.

1y invention relates to linoleum and includ in which there is provided an underlying layer of paper upon which the linoleum substance is mounted and to which such substance adheres. This underlying sheet of paper is preferably provided With-'21 series of parallel strings which are disposed longitudinally of the linoleum strip and are preferably so incorporated within the paper as to be concealed exceptcut in cross section. hese strings serve to prevent the guard against the tearing of the product it issues from the machinery the stretches of string which margin the outer longitudinal edges of the linoleum strip are desirably heavier than stretches of string, formed of a double string, each of a size similar to the remaining strings. The material of which the strings are made is preferably non-metallic, the material employed being desirably linen thread, though the invention is not to be limited to the nature of the threads employed. The paper is preferably made water proof and thisv result is desirablv *ccomplished by providing the bottom face of the paper with a layer of water proof paint, though I do not wish to be limited to this method of making the paper water proof. In order that there maybe proper cdhesion between the paper and the layer of linoleum applied thereto the, paper is uncalendered so thereof freely to pro ect therefrom so as readily to become incorporated with the applied linoleum.

will explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which- Etc 1 is a sectional ohm vim mm- Speciflcation of Letters Patent. Application filed June 11, 1913.

a plane in which the parallel thr ads are disposed. (line 1 l of ig. 2) an intermediate. portion of the product being removed, the gure being taken on a reduced scale excepting for the size of the threads which is neces sarily exaggerated in this figure; Fi 2 is view on an exaggerated scale; ig. 3 IS a detail of construction taken on line 3 3 of Fig. 1 ut on a still further exaggerated scale; and ig. l is a sectional view of the paper taken on a much exaggerated scale amlindicating its fibrous nature.

ike parts are indicated by similar characters of reference throughout the different gures. The layer 1 of linoleum is applied, while in plastic condition and of a temperature having substantially 90 Fahrenheit, to the top face of the underlying strip of paper 2, and as the paper is uncalendered the fibers projecting from the upper side thereof will become thoroughly incorporated with the adjacent portion of the linoleum layer so that when the linoleum has cooled the linoleum and paper will form component parts of an integral productwhich will not be sub ject to separation at their adjacent faces. very suitable paper for this purpose is that commercially known as felt paper. As the uncalendered paper is highly hygroscopic I make it water proof preferably by the application of a bottom coating of water proof paint indicated at 3. The thickness of the entire product is usually either an eighth of an inch or a quarter of an inch. The relathe thicknesses of the linoleum and the paper layers may be substantially as illustrated in Fig. 3.

Owing to the fact that the uncalendered paper lacks necessary tensile strength, an inherent advantage which is sacrificed to permit the fibers oftli paper to become incorporated in the linoleum. the. necessary tensile strength is supplied by a supplemental means preferably in the form of linen threads 4 which extend ongitudinally of the strip of linoleum which is made in the factory in variable lengths say thirteen hundred fifty yards and which is supplied to the trade in lengths of about ninety feet. The linen thread employed is-manufactured by the Clark Thread 'orks and is preferably No. 60. These threads may be spaced three inches or so a art and are preferably continuous from en to end m?
